Melanocytes are found throughout the oral mucosa but usually go unnoticed because of their relatively low level of pigment production. When focally or generally active in pigment production or proliferation they may be responsible for several affections in the oral mucosae ranging from physiologic pigmentation, systemic diseases to malignant neoplasms. The diagnosis of oral pigmentations (OP) is usually challenging for the physician, but a careful examination of the oral cavity may reveal the first manifestation of underlying systemic diseases...

A 66-year-old woman was diagnosed with MRH based on clinical and histopathological findings. The disease had started 6 months before with arthralgia of the right shoulder joint and symmetric xanthelasma on the palpebrae. One month later symmetric, bilateral arthralgia affecting most of the proximal and distal intraphalangeal joints of both hands have occurred. The multiple, asymptomatic, 2-3 mm in size, reddish -NDASH- brown papules adjacent to the proximal nail fold and two larger asymptomatic flesh-coloured nodules located at the extensor surface of the right antebrachium and the dorsal surface of the third right finger have appeared at the same time...

Many dermatologists use teledermoscopy to seek second advice from experts for difficult lesions. Teledermoscopy by primary care physicians (PCP) is still controversial but already has been implemented in several regions. Since there are only few studies published about teledermoscopy in the hand of PCP with poor level of evidence we asked the opinion of dermoscopy experts (board members of the International Dermoscopy Society (IDS)). (1-6) Furthermore, we investigated the routing of patients with a suspicious pigmented skin lesion and the use of teledermoscopy in different countries...

INTRODUCTION: Sunscreen protection in subjects with actinic keratosis (AK) is highly recommended to prevent clinical evolution of this in situ skin cancer condition. Use of topical anti-cyclooxygenase drugs such as diclofenac and piroxicam reduces the number of lesions and improves the cancerization field. A film-forming medical device in a cream formulation containing organic and inorganic sun-filters (50+ SPF) and piroxicam 0.8% (ACTX) has shown in a pilot, single-center, open trial to reduce AK lesions improving the cancerization field...

Importance: Melanomas that clinically mimic seborrheic keratosis (SK) can delay diagnosis and adequate treatment. However, little is known about the value of dermoscopy in recognizing these difficult-to-diagnose melanomas. Objective: To describe the dermoscopic features of SK-like melanomas to understand their clinical morphology. Design, Setting, and Participants: This observational retrospective study used 134 clinical and dermoscopic images of histopathologically proven melanomas in 134 patients treated in 9 skin cancer centers in Spain, France, Italy, and Austria...

OBJECTIVE: Raynaud's phenomenon (RP) is a common cause for consultation. Capillaroscopy is a well-established technique to detect capillary abnormalities suggestive of a connective tissue disease, but it is sometimes unavailable. The aim of this study was to compare dermoscopy and capillaroscopy in the assessment of RP. METHODS: This was a prospective single-centre observational study in adult patients consulting for RP at the Hôpital Nord Franche-Comté between January 2014 and June 2015...

Glomus tumor is a rare benign vascular hamartoma derived from the modified smooth muscle cells of the glomus body. Paroxysmal pain is the leading symptom. A 78-year-old woman presented at our clinic with a 50-year history of a slow growing painful purple blue tender nodule under the right fourth finger nail. Dermoscopy and magnetic ressonance confirmed the presence of a large subungual tumor and total surgical excision was performed after partial nail plate avulsion. Histologic examination confirmed a glomus tumor...

A 74 year-old woman presented with a 9 month history of a slowly enlarging exophytic lesion over her left nasal alar. Examination revealed a firm, cystic mass fixed to underlying skin. It was pedunculated with occasional superficial telangiectasia and a violaceous hue. A differential diagnosis of dermoid or sebaceous cyst, dermatofibroma, and neurofibroma was considered. Histopathological examination confirmed the rare diagnosis of chondroid syringoma (CS), which has a reported incidence of 0.01- 0.098% of excised skin tumors...

Distinguishing benign acral nevi from small early acral melanomas may be challenging in certain cases. Dermoscopy is a noninvasive imaging technique that can help clinicians better visualize deeper lesion structures and thus more easily differentiate benign nevi from melanoma. We report the case of a 13-year-old girl with a changing dark brown to black macule with a central papular component on the volar surface of the right third finger. Dermoscopy revealed asymmetrically distributed irregular black blotches on a bluish-black background...

Porokeratosis is a disorder of epidermal keratinization characterized by the presence of annular hyperkeratotic plaques. Its etiopathogenesis is not yet fully understood, but a relationship with immunosuppression has been reported. Dermoscopic examination revealed a classic yellowish-white ring-like structure that resembled "volcanic crater contour" - the so-called cornoid lamella. We describe a case of porokeratosis in a female patient with chronic lymphedema, which was similar to Bowen's disease due to the many glomerular vessels seen on clinical examination and dermoscopy...

The occurrence of multiple primary melanomas in a single individual is rare. Most commonly, malignant melanocytic lesions subsequent to the initial diagnosis of melanoma are secondary cutaneous metastases. We report a patient with gastrointestinal bleeding from gastric metastasis of cutaneous melanoma. During clinical evaluation and staging, we discovered a brain metastasis associated with 3 synchronous primary cutaneous melanomas. We suggest the research on the mutation in the cyclin-dependent kinase inhibitor 2A (CDKN2A) (INK4a) in such cases...

Alopecia areata is an autoimmune disorder characterized by transient, non-scarring hair loss and preservation of the hair follicle. Hair loss can take many forms ranging from loss in well-defined patches to diffuse or total hair loss, which can affect all hair-bearing sites. Patchy alopecia areata affecting the scalp is the most common type. Alopecia areata affects nearly 2% of the general population at some point during their lifetime. Skin biopsies of affected skin show a lymphocytic infiltrate in and around the bulb or the lower part of the hair follicle in the anagen (hair growth) phase...

Livedoid vasculopathy (atrophie blanche) is a form of thrombotic vasculopathy. It is characterized by small ulcers that become crusted, and heal after several months to produce white atrophic scars. The most commonly affected sites are the lower legs, in particular the dorsum of the feet and ankles. To date, the dermoscopic features of livedoid vasculopathy have not been clearly described in the literature. In this observational study, we sought to evaluate the dermoscopic patterns of livedoid vasculopathy and determine whether the dermoscopic features are associated with certain histopathological characteristics...
